->''"Spinoff"! Is there any word more thrilling to the human soul? Hi, I'm Troy [=McClure=]. You may remember me from such TV spinoffs as ''Son of Sanford And Son'' and ''[=AfterMannix=]''.''
-->-- '''Troy [=McClure=]''', ''WesternAnimation/TheSimpsons'', "The Simpsons Spin-Off Showcase"

Spin-Offs are when part of a successful show, usually characters, but sometimes a general concept ([[Franchise/LawAndOrder first you have the Law, then you have the Order]]), are taken and given a second show of their own.

From a producer's perspective, it's a chance to explore other aspects of a concept. Actors can find opportunities to grow in their craft, as well as rise in importance by moving from just being part of an ensemble to having a show built around them. For the networks, it's a chance to establish a show with a built-in audience, making it that much easier for them to sell advertising.

Lots of spinoffs go on to be successful shows in their own right, sometimes even [[MorePopularSpinoff surpassing the parent series in popularity]]. Others crash and burn (''Joanie Loves Chachi'', anyone?), suggesting that there is no such thing as a sure thing. Nevertheless, networks keep trying them.

!!There are many different kinds of spinoffs including:

* Where a character leaves a show and the two run concurrently. Characters {{Crossover}} from time to time.
* Where a show comes to an end and a character from it is given his or her own new show. Provides an opportunity to {{Retool}} the character as well.
* Where a character is brought on to an existing show simply in order to be spunoff, hopefully making some of the original audience into viewers of the new show (See PoorlyDisguisedPilot).
* The main character is [[TimeSkip revisited elsewhere in his narrative]].
* Reimaginings--the concept is carried into a new show with the same basic premise but other factors and characters are completely new.
* Segment spin-offs--a recurring segment from the show becomes the main attraction.
* A type of {{Defictionalization}}--a ShowWithinAShow gets made into a real show of its own.
* The storyline on one show comes to an end, only to be continued in a new show with a different name.
* [[CompanionShow Official Fanzine Show]]--a trope usually applying to RealityTV, usually offering Behind The Scenes info or coverage that wouldn't fit into the main programme, often (but not always) broadcast immediately after the main show, on a sister channel.
* Online Spin-Off--a spin-off that's only shown online, sometimes overlaps with Segment Spin-Off, sometimes a spin-off InNameOnly. Generally only an advert for the broadcast programme.
* Shared Continuity--more common nowadays, this spinoff generally carries no characters over from the show that spawned it, though both are in the [[TheVerse same continuity]] that allows for {{Crossover}}s from the original.

[=Spinoff=]s are OlderThanYouThink. The character of Falstaff, from ''Theatre/HenryIV'' parts 1 and 2, was given his own play, at Royal request, by Creator/WilliamShakespeare.

See also DistaffCounterpart. When a TV series is successful enough to produce a film [=Spinoff=], this is TheMovie. VideoGame spinoffs often feature the same cast but differing [[VideogameGenres gameplay genres]] or are GaidenGames starring one of the secondary or side characters. When the spin-off focuses on the descendant of a character from a previous installment, it's a SpinOffspring.

In the television industry, there is a technical difference between the terms 'spinoff' and 'sequel': a 'spinoff' refers specifically to a television show that continues in (more or less) the same era as its predecessor, while a SequelSeries takes place ''after'' the parent series' setting.


[[folder:Anime and Manga]]
* ''Manga/FistOfTheNorthStar'' (''Hokuto no Ken'') has a series of spinoff works known as the ''Hokuto no Ken Gaiden'' series, which centers around side-characters from the original manga, depicting what happened to them prior to the events of ''Hokuto no Ken'', although they do deviate from canon a bit. Almost all of them, with the exception of ''Yuria Gaiden'', were published in ''Weekly Comic Bunch'' (the manga anthology that serializes ''[[Manga/FistOfTheBlueSky Souten no Ken]]'') at the time the ''Legends of the True Savior'' movies were released.
* Various side story episodes of [[Anime/{{Pokemon}} the Pokemon anime]] featured former party members after they had left the group. The early ones focusing on Tracey and Misty along with TournamentArc rival Ritchie were dubbed as the ''Pokemon Chronicles'' subseries.
* ''LightNovel/ACertainMagicalIndex'' spawned a spinoff manga in ''Manga/ACertainScientificRailgun'', featuring Mikoto Misaka and delving into her background, friends, and some of the cases which Judgement handles. It later spawned a second manga spinoff, ''[[Manga/ACertainScientificAccelerator A Certain Scientific Accelerator]]'', following Accelerator and the events after he receives his drama-preserving handicap
** ''Railgun'' then spawned a third manga spinoff, ''A Certain Scientific Railgun Gaiden: Astral Buddy'', starrring a minor character from said manga. Yup. A spinoff of a spinoff.
%% * ''Betterman'' --> ''BettermanLegends''
%% * ''Manga/OutlawStar'' --> ''Anime/AngelLinks''
* The ''Franchise/LyricalNanoha'' franchises is one long string of these and even started as a spin-off of ''VisualNovel/TriangleHeart3SweetSongsForever''. Within the current canon there's the [[Anime/MagicalGirlLyricalNanoha original series]] and [[Anime/MagicalGirlLyricalNanohaAs its]] [[Anime/MagicalGirlLyricalNanohaStrikers three]] [[Manga/MagicalRecordLyricalNanohaForce sequels]], an [[Audioplay/StrikerSSoundStageX audio play]] spin-off focusing on characters introduces in the third season, a SpinOffspring [[Manga/MagicalGirlLyricalNanohaVivid manga]] focusing on Nanoha's adopted daughter, a [[Anime/VividStrike spin-off]] of the SpinOffspring focusing on brand new characters, and [[Manga/MagicalGirlLyricalNanohaINNOCENT an alternate universe manga]] where everyone plays card games.
* ''Manga/DragonBall'' has an anime follow-up named ''Anime/DragonBallGT'', set some years after the end of ''Anime/DragonBallZ'', trying to get back the series to his comedic roots with Goku reverting to a child. It is not based on {{Creator/Akira Toriyama}}'s original manga [[note]]The manga ends with Goku departing with Uub, the same ending as Dragon Ball Z[[/note]],so the original author only contributed on character designs. WordOfGod stated GT was a side story to the original series.
** In 2015, ''Anime/DragonBallSuper'' premiered -with a manga running concurrent-, being an interquel between the Buu Saga and Goku and Uub's departure, integrating Movie characters Beerus and Whis and concepts like Alternate Universes to the franchise. This time, Akira Toriyama writes the plot outline and Creator/{{Toyotaro}} makes some plot additions and even designed some Gods of Destruction.
** There is also a short manga named Dragon Ball Side Story: Yamcha Isekai, where a teenager going to a Dragon Ball event suddenly dies and awakes into the Dragon Ball world as Yamcha, and tries to change the fate of said character.

* There was a Manga called Ten, which was about mahjong being serious business, there was a character called Akagi which was an awesome old man who the characters feared and respected, the character was so popular the author made an spinoff prequel series focused on Akagi's early life, at one point he meets his match in an old man called Washizu, who was so popular the author made a spinoff series focused on Washizu's early life (yes, Fukumoto made a spinoff of a spinoff).
* ''Manga/MyHeroAcademia'' has ''Manga/VigilanteMyHeroAcademiaIllegals'', set a few months before the main series. It focuses on a group of vigilante heroes trying to prevent the PsychoSerum Trigger from spreading.
** Another one is '' My Hero Academia Smash!!'', which is a gag manga showing the characters in chibi form.
* ''Manga/{{Naruto}}'' --> ''Rock Lee's Springtime Of Youth'', a comical spinoff focusing on Rock Lee.
** Also ''Sasuke Uchiha's Sharingan Legend'', another comical spinoff showing Sasuke and Taka's wacky side.
* ''Manga/OnePiece'' has a few:
** ''Chopperman'', which stars Chopper as a super hero fighting against the evil Dr. Usodabada. It was initially a gag story in one of the databooks, before it was adapted into its own spin-off manga.
** ''One Piece Party'', a LighterAndSofter comedic spinoff with self-contained stories and SuperDeformed designs.
%% * ''Manga/InuYasha'' --> ''Kagome the Adventurer''
%% * ''Manga/CrayonShinChan'' --> ''Manga/ActionMask''
* ''Manga/{{Genshiken}}'' --> ''Anime/KujibikiUnbalance'' was initially a ShowWithinAShow, meant to represent the typical {{moe}} anime, but with the series' success, it ended up being {{defictionalized}}.
* ''Manga/JoJosBizarreAdventure'' has a spin-off with the ''Thus Spoke Rohan Kishibe'' series, consisting of several irregularly published one-shots starring Rohan Kishibe, a side character from the manga's fourth part ''Diamond is Unbreakable''. These one-shots features beings more esoteric than Stands and vampires, such as original cryptids and other powerful spirits, some considered gods. Although characters from Part 4 regularly appear, it can be inferred that the spin-off is in a different continuity than the current part.
* ''Anime/NeonGenesisEvangelion'' has the manga series ''Manga/ShinjiIkariRaisingProject'', based in the video game of the same name. It takes the alternate reality from Episode 26 as inspiration, and as such is more comedic and most of its characters are much more emotional stable, all while keeping their most notable traits, albeit more subdued.
** Before that, there was Neon Genesis Evangelion: Angelic Days, based on the eponymus game as well. As with the above example, its characters are alternate versions of the main continuity. It ended with a much happier ending than the anime.

* A concrete anime example is ''VisualNovel/ToHeart2'', which takes place in the same school as the original ''VisualNovel/ToHeart'', only that it is set three years after. Some [[ContinuityNod nods]] and [[ContinuityCameo cameos]] reinforce this.
* ''Anime/PuellaMagiMadokaMagica'' has ''Manga/PuellaMagiKazumiMagica'', which is about another group of {{magical girl}}s. Its other spin-off, ''Manga/PuellaMagiOrikoMagica'' is either a {{Prequel}} or an {{Interquel}}. A third spin-off entitled ''Puella Magi Madoka Magica: The Different Story'' was released for the CompilationMovie, and it is part {{Prequel}}, POVSequel, and WhatIf story. Three new spin-offs began after the premiere of ''Anime/PuellaMagiMadokaMagicaTheMovieRebellion''. One is an ''Oriko Magica'' {{prequel}}. The other ones are ''Manga/PuellaMagiSuzuneMagica'', which is about another group of magical girls, and ''PuellaMagiTartMagica'', which elaborates on a [[BeethovenWasAnAlienSpy background detail]] from the anime.
* ''Anime/PleaseTwins'' is set one year after the events of ''Anime/PleaseTeacher'', it shares most locations and many of the first anime characters come back either as cameo or secondary characters.
%% * ''Anime/YuGiOh'' --> Anime/YuGiOhGX --> Anime/YuGiOh5Ds --> Anime/YuGiOhZexal
* ''Franchise/{{Jewelpet}}'' --> ''Anime/JewelpetTwinkle'' --> ''Anime/JewelpetSunshine'' --> ''Jewelpet Kira Deco!'' --> ''Jewelpet Happiness'', all of the series shares the same Jewelpets, but not the same characters in general to prevent canon confusion.
* ''Manga/AttackOnTitan'': ''Attack On Titan Levi Side Story: A Choice With No Regrets'' manga, which is based on the ''Choice With No Regrets'' visual novel included with the ''Attack On Titan'' Vol.3 Blu-ray. This spin-off features Levi as the main character and serves as a prologue to the main series.
* ''Manga/FairyTail'': Several have been serialized:
** ''Fairy Tail Zero'', an OriginStory starring [[BigGood Mavis Vermillion]] about the founding of Fairy Tail
** ''Tale of Fairy Tail: Ice Trail,'' which is another OriginStory about Gray Fullbuster.
** ''Fairy Tail: Blue Mistral'', another one focused on Wendy and Carla.
** ''Fairy Girls'', which as the name implies, has the female members of Fairy Tail as the main characters.
** Also, there's a Gaiden sub-series written by Kyouta Shibano:
*** ''Fairy Tail Gaiden: The Twin Dragons of Sabertooth'', which is focused on Sting and Rogue.
*** ''Fairy Tail Gaiden: Rhodonite'', focused on Gajeel.
*** ''Fairy Tail Gaiden: Flash of Great Lightning, detailing the events of Laxus and the Raijinshu during [[spoiler:Fairy Tail's disbandment.]]
* ''Manga/FateKaleidLinerPrismaIllya'': a spinoff MagicalGirl story involving [[CuteBruiser Illya]] as the protagonist.
* ''Manga/SaintSeiya'' produced a ''crapton'' of spin-offs:
** ''Manga/SaintSeiyaEpisodeG'', drawn by Okada Megumu, who focuses on Gold Saint Aiolia long before the main series. It produced its own spin-off, ''Manga/SaintSeiyaEpisodeGA''.
** ''Manga/SaintSeiyaTheLostCanvas'', another prequel, as well as ''The Lost Canvas Chronicles''.
** ''Manga/SaintSeiyaNextDimension'', a sequel drawn by Kurumada himself.
** ''Manga/SaintSeiyaSaintiaSho'', which takes place during the events of the main series but focuses on female protagonists.
** ''Anime/SaintSeiyaOmega'', a 2012 animated series following a new generation of Saints.
* ''WWW.WORKING!!'' to ''Anime/{{WORKING}}'', focusing on a different set of employees at a different branch of the Wagnaria restaurant. Franchise wise, the latter is this to the former; anime wise, it's the opposite case (being based off of the print collection rather than the original webcomic, which was made long after the latter got its time in the animated sun).
* ''Brave Witches'' to ''Anime/StrikeWitches'', shifting the focus from the 501st to the 502nd Striker Unit.

[[folder:Audio Play]]
* ''Series/DoctorWho'' --> ''AudioPlay/BigFinishDoctorWho'' --> ''AudioPlay/SarahJaneSmith'', ''AudioPlay/IDavros'', ''AudioPlay/{{UNIT}}'', ''AudioPlay/CounterMeasures'', ''AudioPlay/{{Cyberman}}'', ''AudioPlay/{{Gallifrey}}'', ''AudioPlay/JagoAndLitefoot'', ''AudioPlay/KaldorCity'', ''AudioPlay/DalekEmpire'' The main Big Finish line is [[BroadStrokes broadly]] part of the Franchise/{{Whoniverse}}, while the spinoffs are part of the Franchise/DoctorWhoExpandedUniverse.
* ''AudioPlay/YandereHeaven'' gets a special BL edition called ''Yandere Heaven [=BLack=]''. It features very similar situations, but with a male protagonist instead of female.

%% * ''ComicBook/{{Horndog}}'' --> ''ComicBook/HereWolf''
%% * ''{{ComicBook/Fables}}'' --> ''ComicBook/JackOfFables''
* The second volume of ''ComicBook/{{Runaways}}'' had a PoorlyDisguisedPilot for ''ComicBook/TheLoners'', a miniseries featuring a group of former teen heroes making questionably-sincere attempts to quit the hero business.
%% * ''ComicBook/ArchieComicsSonicTheHedgehog --> ''Knuckles the Echidna'' and ''Sonic Universe''.
* ''ComicBook/TheSandman'' has several spin-offs following supporting characters, including:
** ''ComicBook/{{Lucifer}}'', which follows the adventures of Lucifer after he quits being Ruler of Hell in ''The Sandman: Season of Mists''.
** ''ComicBook/TheThessaliad'' and ''ComicBook/ThessalyWitchForHire'', in which Dream's murderous ex-girlfriend Thessaly deals with new problems brought on by a ghost named Fetch.
* ComicBook/TheMightyThor: Has a interesting relationship with Journey into Mystery. Thor debuted in ''Journey into Mystery'' and headlined it for a while before taking over the title completely and later getting another series. 49 years after his debut, ''Journey into Mystery'' is introduced as a spin-off taking over Thor's numbering and Thor gets another series.
* Comicbook/FantasticFour After the death of a prominent member of the book, the book ended at issue 588 and was revamped as ''FF'' (FF in the title standing for Future Foundation). After 11 issues of FF, Marvel revived the Fantastic Four for issue 600 (the previous issues being ''FF'') and it will continue forward with ''FF'' also being released concurrently focusing on the non Fantastic Four members of the Future Foundation.
* ''ComicBook/BatwomanRebirth'' is a spinoff from a story arc in ''ComicBook/DetectiveComicsRebirth'' called "Batwoman Begins". That arc involves a new kind of bioweapon, and in the spinoff series, Batwoman tracks down those who traffic in said weapon.
* ''ComicBook/TheAuthority'' began as a spin-off of ''ComicBook/{{Stormwatch}}''. It later spawned two spin-offs of its own - ''ComicBook/TheMonarchy'', about the surviving members of Stormwatch, and ''ComicBook/{{Kev}}'', about a hapless SAS operative who keeps having to team up with the Midnighter. There was also a very short-lived ''Midnighter'' solo series.
** Speaking of ''Stormwatch'', its original incarnation spawned a spin-off about ComicBook/{{Backlash}}.

* ''Film/{{Grindhouse}}'' featured a FakeTrailer for ''Film/{{Machete}}'' which later became a film of its own. WordOfGod also states that the Machete from ''Film/SpyKids'' is the same Machete, so it also counts for that film.
* ''The Graveyard'' ([[RetroactiveRecognition notable]] for featuring Mark Salling, pre-''Series/{{Glee}}'') exists in the same universe as the ''Bloody Murder'' duology.

* Plantagenet Palliser, a minor character in ''The Small House at Allingham'', one of ''Literature/TheChroniclesOfBarsetshire'' by Creator/AnthonyTrollope, became a main character of Trollope's Literature/{{Palliser}} series, written in the 1860s and 1870s.
%% * ''Literature/{{Private}}'' --> ''Privilege''
* The Literature/DoctorWhoNewAdventures were published by Virgin Publishing under license from the BBC. When the BBC decided to take the license back to start publishing their own Literature/EighthDoctorAdventures, Virgin spun off the ''Franchise/BerniceSummerfield'' novels, which continued to tell similiar sci-fi adventure stories using characters and worldbuilding elements that had been created for the New Adventures (and which Virgin consequently retained rights to) or which could be licensed separately from the writers that had created them.
* One of the Literature/EighthDoctorAdventures novels by Lawrence Miles introduced Faction Paradox, an association of anarchic time-traveling villains. After leaving the series, Miles instituted his own series of ''Literature/FactionParadox'' novels.
* Telos published a series of ''Series/DoctorWho'' novellas; one of them, ''Cabinet of Light'', introduced a set of characters who were spun off in to the ''Literature/TimeHunter'' series.
* P. D. James's Adam Dalgliesh detective novels spun off a short line of two novels about private investigator Cordelia Gray, including a surprise {{cameo}} by the original detective.
* ''Literature/TheIliad'' and the ''Literature/TheOdyssey'' both cover the same story but through different cultural lenses. ''Literature/TheAeneid'' also follows the adventures of a minor character from ''The Iliad'', but it was written by a different writer hundreds of years later.
%% * ''Gotrek and Felix'' --> ''Thanquol and Boneripper''
%% * ''Gotrek and Felix'' --> ''Ulrika the Vampire''
* ''Literature/SweetValleyHigh'' gave us... dear lord. There were ''eight different spin-offs'' of Sweet Valley High, all but one of them also being about the twins that served as main characters at various points in their lives. The seven that were about the twins were Sweet Valley Twins, Sweet Valley University, Sweet Valley Kids, Sweet Valley Junior High, Sweet Valley Senior Year, Elizabeth, and The Sweet Life. The last spin-off The Unicorn Club takes place when the twins are in middle school but focuses on the club instead.
%% * ''Literature/TheHardyBoys Mystery Stories'' --> ''The Hardy Boys Casefiles'' (for older readers)

%% * ''Literature/NancyDrew Mystery Stories'' --> ''The Nancy Drew Files'' (for older readers)
%% ** ''Nancy Drew Mystery Stories'' --> ''Nancy Drew: Girl Detective'' --> ''The Nancy Drew Diaries'' (May or may not all take place in the same universe; hard to tell. If so, it would be new adventures of a character.)
%% ** ''Nancy Drew Mystery Stories'' --> '' The Nancy Drew Notebooks'' --> ''Nancy Drew and the Clue Crew'' (for younger readers)
* The ''Literature/MercyThompson'' series has the spin-off series ''Alpha and Omega'' which follows a character introduced in the first book and his wife. A few short stories focusing on other side character are also set in the same universe.
* The ''Literature/TheInfernalDevices'' series has a spin-off ''Literature/TheMortalInstruments''. It is an interesting example; the two series share a couple characters, (namely, Magnus and Camille), but they're not central to either series, and all the other characters are new. Plus, "The Infernal Devices" takes place 200 years before "The Mortal Instruments".
%% * Literature/DenOfShadows --> Literature/KieshaRa
* ''Literature/ShamanBlues'' is a spin-off to ''Literature/DoraWilkSeries'', with the main character of the former being a character from the latter who was PutOnABus for larger parts of the series.

[[folder:Live Action TV]]
* ''Series/{{Dallas}}'' gave rise to the show ''Series/KnotsLanding''. Interestingly enough, ''Knots Landing'' was actually shopped first to CBS, but rejected. When ''Dallas'' took off, they inserted one of the Ewing brothers and re-shopped KL as a spin-off. Interesting in that when an entire season of Dallas was retconned to have been AllJustADream, this also meant that the ''entire spin-off'' had to be either AllJustADream as well, or not a spin-off after all.
* ''Series/BuffyTheVampireSlayer'' spun off ''Series/{{Angel}}'', featuring the ''Buffy'' main characters of Angel and Cordelia, with the guest character Wesely joining later in the series. Crossovers between the two were frequent until _Buffy_ moved to a new network.
* ''Series/BeverlyHills90210'' had a spin-off ''Series/{{Melrose Place}}'' within less two years of its introduction, which itself spun off a not-as-successful spin-off ''Models Inc.'', which lasted a season
* ''Series/DoctorWho'' --> ''Series/K9AndCompany'', ''Series/{{Torchwood}}'', ''Series/TheSarahJaneAdventures'', ''Series/{{K9}}'' All are part of the Franchise/{{Whoniverse}} which revolves around the Doctor, but the only thing linking ''K9'' to the Whoniverse is the presence of the eponymous robot dog. ''K9'' was not produced by the BBC, so it cannot directly reference ''Doctor Who'' and vice versa.
** In the early 2000s, there were four ''Series/DoctorWho'' online animated specials featuring the Sixth, Seventh and Eighth Doctors, and an alternate Ninth Doctor.
* ''Series/HerculesTheLegendaryJourneys'' --> ''Series/XenaWarriorPrincess''. Xena was introduced as villain who considered Hercules a WorthyOpponent, but a short-lived romance between the two convinced her to become a hero herself, and her own series revolves around her redemption from her warlord past.
* ''Series/GreysAnatomy'' --> ''Series/PrivatePractice''
* ''Series/AllInTheFamily'' spun off no fewer than ''three'' shows, some of which had their own spinoffs:
** ''Series/TheJeffersons'' whose housekeeper Florence later received her own spin-off ''Series/CheckingIn'', which was cancelled after four episodes.
** ''Series/{{Maude}}'', whose housekeeper Florida, was spun off into ''Series/GoodTimes''. It also kind of a sequel, as ''Series/AllInTheFamily'' became ''Series/ArchieBunkersPlace''. Similarly, but less successfully,
** ''Series/ArchieBunkersPlace'' itself had a one season spin-off ''Gloria'' that featured Archie's daughter [[ExactlyWhatItSaysOnTheTin Gloria]] , having divorced Mike, starting a new life in New York.
** The last gasp of the franchise came in 1994, with yet another (short-lived) spinoff: ''704 Hauser'', about the people who were then living in what had been Archie's house. The adult Joey Stivic (son of Michael and Gloria) drops by for a visit in the first episode.

* ''Series/TheXFiles'' featured a trio of recurring characters, conspiracy theorists, known as The Lone Gunmen. They were spun off into their own short-lived eponymous show, ''Series/{{The Lone Gunmen}}''
%% * ''Series/TheVampireDiaries'' --> ''Series/TheOriginals''
* ''Series/StarTrekTheOriginalSeries'' gave rise to a whole universe of spin-offs:
** ''Assignment Earth'' a proposed spin-off with a PoorlyDisguisedPilot which never ended up happening.
** ''Series/StarTrekTheNextGeneration'' which focused on the another ship that was given the name ''Enterprise'' and was set approximately a century after the original.
** ''Series/StarTrekDeepSpaceNine'' was spun off of the Next Generation while ''TNG'' was still airing. Recurring character Chief Miles O'Brien (and eventually Worf as well) left ''TNG'' to become a main character on ''[=DS9=]'', and there were substantial crossovers between the two shows in the [=DS9=] pilot "Emissary" and the TNG episode "Birthright Part 1". ''[=DS9=]'' is thus the sole example in ''Star Trek'' of a parallel story spinoff: the others are a type of shared continuity, as listed below.''
** 'Series/StarTrekVoyager'': the spinoff picks up almost immediately after the conclusion of ''TNG'', and although it does not feature any continuing characters, it does continue various stories and themes originating from ''TNG'' and ''[=DS9=]''.
** ''Series/StarTrekEnterprise'' is set more than 110 years before ''The Original Series'', and is arguably a spinoff of ''TOS'', ''TNG'' or both.
** Each ''Franchise/StarTrek'' series featured few crossovers, apart from one at the beginning of each spinoff as a symbolic "passing the torch". The first episode of ''TNG'' included a cameo appearance by an aged Dr [=McCoy=]; the pilot of ''[=DS9=]'' (listed as parallel stories) prominently featured Captain Picard; the first scene of ''VOY'' included a cameo by ''[=DS9=]'''s Quark; the first episode of ''ENT'' showed a video recording of Dr Zefram Cochrane, a major character in the ''TNG'' film ''Film/StarTrekFirstContact''.
* When ''Series/{{Cheers}}'' ended, Frasier Crane left Boston to move back home to Seattle, becoming the main character of his own show, ''Series/{{Frasier}}''. Crossovers with characters form Cheers were frequent, with all of Sam, Diane, Lilith, Carla, Norm, Cliff, and Woody all making appearances at one point or another.
** ''Cheers'' actually had a prior spinoff, ''Meet the Tortellis'', featuring Carla's ex-husband. The show did not last very long.

* ''Series/InspectorMorse'' spun off into ''Series/{{Lewis}}'' with a minor TimeSkip. The series picked up in 2007 after ''Inspector Morse'' ended in 2000.
* ''Series/ThatsSoRaven'' spun into ''Series/CoryInTheHouse'' after a small TimeSkip. ''CITH'' takes place some time after ''TSR'', after Raven goes to college.
* ''Caerdydd'' spun into ''Gwaith Cartref''. Neither Emyr nor Sara mentions Lea, Peter, or any of the other characters from the earlier show which is strange, given how it ended.
* ''Series/ICarly'' set up a spinoff built around Gibby that never got past a pilot. On the other hand, Sam as well as Cat from ''Series/{{Victorious}}'' went on to, well, ''Series/SamAndCat''.

The series focus on Saul's life before he was lawyer under his real name (Jimmy [=McGill=]) and also shows what happened to him after the events of Breaking Bad, serving as both a prequel and a sequel to the main series as well.

* ''Series/ThePractice'' had the spin off ''Series/BostonLegal'', where the spinoff was designed around characters originally introduced in the original in a serious case of FinalSeasonCasting.
* ''Series/{{Arrow}}'' spun into ''Series/TheFlash2014''. The titular character of the latter show was introduced in - and gained his powers at the end of - a two-parter in the middle of Arrow's second season. Episode 2x20 was originally going to be a BackdoorPilot before the execs decided to make it a standalone episode.

* ''Series/StargateAtlantis'' and ''Series/StargateUniverse'' both spun-off of the show ''Series/StargateSG1'' which itself was based on the film ''Film/{{Stargate}}''. Atlantis is set in the lost city of Atlantis and features characters from the first series such as Major Carter who ran the installation in later seasons. Universe was set after both in continuity and the setting meant that old characters showed up far less often.
* ''Series/BattlestarGalactica2003'' --> ''Series/{{Caprica}}'', a prequel spinoff which follows the creation of Cylons ~50 years before the setting of the parent show.
%% * The various ''Series/{{CSI}}'' and ''Franchise/LawAndOrder'' spinoffs.
* The first seven seasons of ''Franchise/PowerRangers'' used a few old characters mixed with new ones. Starting with ''Lightspeed Rescue'', they used the no character variant, all set in the same universe, with characters only returning for team-up episodes. The exceptions were ''Series/PowerRangersDinoThunder'' and ''Series/PowerRangersSamurai'', where Tommy and Bulk returned as main characters, respectively.
* ''Series/{{Eureka}}'' and ''Series/{{Warehouse13}}'' are established as a shared canon during an episode on each show in which each had a character visiting from the other. There was also a brief appearance of a recurring Series/{{Warehouse13}} character in an episode of ''Series/{{Alphas}}'', putting all three series in one universe.
%% * ''Series/OnceUponATime'' --> ''Series/OnceUponATimeInWonderland''
* ''FiveFwd'' is the parent show for Channel Five's ''TheGadgetShow'' and ''FifthGear''. The former features a formalised news segment which has never been part of the main programme with a different presenter and games reviews and interviews with one of the regular presenters- something that rarely appears in the show proper.
%% * ''Series/{{Monk}}'' --> ''Little Monk''
%% * ''Series/SonnyWithAChance'' --> ''Mackenzie Falls''
%% * ''Series/UglyBetty'' --> ''Mode After Dark''
%% * ''Series/{{Offspring}}'' --> ''The Nurses''
* ''Series/EastEnders'' had a spin-off ''E20'' following a group of teenagers outside of the main cast. Some were later promoted to the main series.
%% * ''Series/ThirtyRock'' --> ''Frank vs Lutz'' and ''Jack Donaghy: Executive Superhero''.
* ''Series/{{Being Human|UK}}'' had an online spinoff called ''Series/BecomingHuman'' which focused on Adam, a charater that had featured in an episode of the parent show, and otherwise entirely new characters.
* You probably wouldn't expect a Ken Burns documentary series, let alone that within his Great American Trilogy, to have one, but ''Baseball'' does--specifically, a 2016 two-part miniseries following the life of Brooklyn Dodgers player Jackie Robinson.
* After Steve Wilkos left ''Series/TheJerrySpringerShow'' after being the director of security there, he was given his own series, ''Series/TheSteveWilkosShow'', which deals with ''much'' more serious topics.
* The Australian game show ''Hard Quiz'' was spun off from ''The Weekly with Charlie Pickering'', specifically the regular segment ''Hard Chat''. In one episode, a contestant's special subject was ''Series/HappyDays'', and when Tom Gleeson brought up the ''Series/LoveAmericanStyle'' example, he then went on to [[BlatantLies claim]] that ''Hard Quiz'' was, in contrast, completely original.
* In 2013, ''Series/{{Ultraman}}'' was awarded by the Guinness Book of World Records with [[http://www.crunchyroll.com/anime-news/2013/09/12/video-ultraman-gets-guinness-record-for-most-spin-off-shows the record for most spin-offs]] (which form the ''Franchise/UltraSeries'' franchise). There were 27 series in 2013, and in 2017 there were 30 series, with the number increasing with every year. Ironically, ''Ultraman'' itself is a MorePopularSpinOff of ''Series/UltraQ'', but since the former show is [[PopularityPower better known worldwide]], it gets the award instead.
* ''Series/AgentCarter'' spun off from ''Film/CaptainAmericaTheFirstAvenger''. Peggy Carter was Cap's main love interest in the 40's, and her show is about her moving on with her life and having adventures of her own after he was [[HumanPopsicle frozen in the Arctic]] and presumed dead. Had the show not been cancelled after 2 seasons, it would have showed her founding SHIELD with Film/IronMan's father Howard Stark.

[[folder:Professional Wrestling]]
* The Heartland Wrestling Association was one to Wrestling/{{WCW}}, Adrenaline being one to [[Wrestling/WCWMondayNitro Nitro.]] Focusing mainly on developmental wrestlers who may or may not "graduate" to WCW's main roster or elsewhere, Heartland ended up running shows and training successful wrestlers well after WCW went out of business.
* Oz Academy was originally based around Mayumi Ozaki's attempts to train new wrestlers for the PowerStable of the same name [[VillainBasedFranchise to aid her in her campaign]] against the GAEA promotion. After GAEA closed down, Oz Academy became increasingly self contained, though a rivalry with GAEA's would be successor Sendai Girls Pro Wrestling periodically rises to the surface.
* Strangely, Pro Wrestling RESPECT started out as a spin off to both Wrestling/RingOfHonor and Wrestling/{{SHIMMER}}, focused mainly around the students of their academy. However, it eventually drifted into "Wrestling Is Respect", one of many "Wrestling Is" promotions that serve as spin offs to Wrestling/{{Chikara}}(and ended up being the longest lasting of them).
* Although inheriting its name from Wrestling/{{ECW}}'s training facility, when House Of Hardcore started doing their own shows they began as spin off of Family Wrestling Entertainment, as school head Wrestling/TommyDreamer was their champion. The crowd reaction pretty quickly established that HOH was better off not trying to be a family show though.
* The Scotland based Insane Championship Wrestling opened a sister promotion called Fierce Females in 2012, in order to give more focus to said group. However, FF and ICW parted ways in 2014 and ICW started a women's division that ran on the same shows as all its other talent instead.
* Ring Ka King was to be a spin off of Wrestling/{{TNA}} based in India, though after a single televised season the two promotions broke away from one another and RKK went dormant.
* New Borinquen Pro Wrestling was a developmental territory of The World Wrestling League that was based around independent circuit and former IWA Puerto Rico wrestler tryouts, in addition to a stronger focus on "strong style" ([[Wrestling/NewJapanProWrestling if the name didn't make that clear]]). It is another "farm league" that has chugged along after its larger partner closed down. And it didn't return to being its farm league when WWL started back up.
* Wrestling/{{CZW}} started "Dojo Wars" in 2014, based around the students of its dojo and those (hopefully) destined for Wrestling/{{WSU}}'s locker room. Sometimes they get into scuffles with students from other wrestling schools.[[/folder]]

* The rare example of the nonfiction spinoff: ''Radio/ThisAmericanLife'' --> ''Podcast/{{Serial}}''. ''Serial'' takes the essential format of a ''This American Life'' investigative story (which typically lasts 15-20 minutes, although sometimes it can take a whole hour) and stretches it out over a twelve-episode season's worth of 45-minute(ish) episodes. It was explicitly called a spinoff by the ''TAL'' crew, features ''TAL'' producer Sarah Koenig as its presenter/investigator/producer, and inherits a lot of both personnel and style from the mothership. It was also launched by a [[PoorlyDisguisedPilot completely undisguised pilot]], in which the first episode of ''Serial'' was aired as an episode of ''This American Life'' (Episode #537, "The Alibi").
%% * ''Radio/FibberMcGeeAndMolly'' has ''The Great Gildersleeve'' & ''Beulah''. Beulah was the first radio show to eventually star an African-American performer, and successfully moved to television.
* ''Radio/ImSorryIHaventAClue'' was spun off from ''Radio/ImSorryIllReadThatAgain'', featuring (at first) most of the same performers (plus Humphrey Lyttelton as chairman) but in a ridiculous PanelGame rather than a SketchShow. It has been running [[LongRunners since 1972]], far [[MorePopularSpinOff surpassing]] the original (which had a very respectable run itself).
** ''Radio/ImSorryIHaventAClue'' eventually got a SpinOff of its own. In one of the games, which involves improvising a comedic dialogue that suggests the title of a book, film etc. (usually by way of an elaborate pun), one pair of contestants would usually adopt the characters of a pair of eccentric Scotsmen, exchanging numerous puns and double-entendres along the way. These characters were spun off into their own scripted comedy series, ''You'll Have Had Your Tea: The Doings of Radio/HamishAndDougal''.
%% * SoundToScreenAdaptation example: "Dave Hollins Space Cadet" in ''Son of Cliche'' --> ''Series/RedDwarf''

* As mentioned in the description text, one of the earliest known spinoffs comes from the work of Creator/WilliamShakespeare: the character of Falstaff, an amalgam of several 14th- and 15th-century figures, who appeared as a secondary character in ''Theatre/HenryIV'' (both [[Theatre/HenryIVPart1 Part 1]] and [[Theatre/HenryIVPart2 Part 2]]), who was given his own play in the form of ''Theatre/TheMerryWivesOfWindsor''.

[[folder:Video Games]]
* ''VisualNovel/PhoenixWrightAceAttorney'' had a spin off series. ''VisualNovel/AceAttorneyInvestigationsMilesEdgeworth'' was a mystery solving game and featured the prosecutor from the first game as the main character.
%% * ''VideoGame/{{Lemmings}}'' --> ''VideoGame/TheAdventuresOfLomax''
* The ''VideoGame/{{Portal}}'' [[VideoGame/{{Portal2}} series]] is a spinoff from ''VideoGame/HalfLife''. It features new characters and setting, but has references to the events of Half-Life.
* The ''Franchise/ShinMegamiTensei'' series has several concurrent timelines, with the main timeline and the ''[[VideoGame/ShinMegamiTenseiIf if...]]''/''[[Franchise/ShinMegamiTenseiPersona Persona]]'' timeline being the most notable ones. ''[[VideoGame/ShinMegamiTenseiNocturne Nocturne]]'' implies that many if not all the timelines are canon within the same multiverse. ''Shin Megami Tensei'' itself was a spinoff of the original ''Megami Tensei'' games on the Famicom, although the name change was mostly due to [[WritingAroundTrademarks trademark reasons]], as the original ''VideoGame/MegamiTensei'' was a tie-in to the first book in Aya Nishitani's ''Literature/DigitalDevilStory'' series.
** The ''[[Franchise/ShinMegamiTenseiPersona Persona]]'' RPG subseries itself has multiple spin-offs. ''VideoGame/Persona4Arena'' and ''VideoGame/Persona4ArenaUltimax'' are fighting game sequels to ''VideoGame/Persona3'' and ''VideoGame/Persona4'', ''VideoGame/Persona4DancingAllNight'' is a RhythmGame sequel to ''VideoGame/Persona4'', and ''VideoGame/PersonaQShadowOfTheLabyrinth'' is a crossover of ''Persona 3'' and ''4'' with ''VideoGame/EtrianOdyssey''-style gameplay.
* The ''VideoGame/DynastyWarriors'' franchise was successful enough to spawn quite a few spinoffs. The spinoffs basically just take the original mob hack'n'slash gameplay formula of Dynasty Warriors, and apply it to different settings and universes. Some of them are even licensed properties, such as anime, manga, or other video game franchises.
** The ''Empires'' expansions are spinoffs of the main games. They contain the same hack'n'slash core gameplay for battles, but with a more strategic approach, allowing for battle formations, politics, kingdom-building, and simulation.
** ''VideoGame/SamuraiWarriors'' originally started as a spinoff to Dynasty Warriors. Its popularity and success has lead it to becoming its own separate series, with its own spinoffs, sequels, and expansions. Yep, this is a spinoff that spawned spinoffs of itself.
** ''VideoGame/WarriorsOrochi'' was a spinoff that brought the cast of Dynasty Warriors and Samurai Warriors together.
** ''VideoGame/DynastyWarriorsGundam'', crossed over with the Gundam franchise.
** ''VideoGame/FistOfTheNorthStarKensRage'', based on Manga/FistoftheNorthStar.
** ''VideoGame/OnePiecePirateWarriors'', based on the popular manga Manga/OnePiece.
** ''VideoGame/HyruleWarriors'', based on the ''Franchise/TheLegendOfZelda franchise''. It is also one to ''The Legend Of Zelda''. A non-canon entry handled by Tecmo-Koei that uses gameplay similar to ''Dynasty Warriors'' but with a ''Zelda'' twist (like incorporating ''Zelda'' items into combat). It's basically [[JustForFun/XMeetsY Zelda meets Dynasty Warriors]].
** ''Arslan: The Warriors of Legend'', based on the 2015 anime adaptation of Literature/TheHeroicLegendofArslan.
** ''[[VideoGame/BerserkandtheBandoftheHawk Berserk and the Band of the Hawk]]'', based on Manga/Berserk.
** ''VideoGame/MusouStars'' was a spinoff that incorporated characters from across Koei Tecmo's intellectual properties.
** ''VideoGame/FireEmblemWarriors'', based on the Franchise/FireEmblem video game franchise. Like Zelda above, is also one to the ''Fire Emblem'' franchise, as well as a non-canon entry handled by Tecmo-Koei that uses gameplay similar to ''Dynasty Warriors'' but with a ''Fire Emblem'' twist (like incorporating Fire Emblem strategic elements into combat). It's basically [[JustForFun/XMeetsY Fire Emblem meets Dynasty Warriors]]
* The ''[[Franchise/SuperMarioBros Mario]]'' franchise has ''loads'' of spinoffs. ''VideoGame/MarioKart'', ''VideoGame/MarioParty'', ''VideoGame/MarioGolf'' and other sports just to name a few. ''Mario'' itself is a spinoff of the ''Franchise/DonkeyKong'' series, though the latter is treated as a spinoff of the former by most people, including Nintendo.
** The ''VideoGame/{{Wario}}'' and ''VideoGame/YoshisIsland'' series are spinoffs of the ''Mario'' series that have developed enough of their own identity to be considered franchises in their own right.
** ''VideoGame/SuperMario3DWorld'' gave Captain Toad, whom originated from ''VideoGame/SuperMarioGalaxy'', his own personal levels. They served as a sort of [[BackdoorPilot backdoor pilot]], as they eventually spun-off into their own full-fledged game: ''VideoGame/CaptainToadTreasureTracker''.
* ''VideoGame/FistOfTheNorthStar2018'' to ''VideoGame/{{Yakuza}}'': a licensed spin-off based on the ''Manga/FistOfTheNorthStar'' series, placing the characters and setting of the manga into the ''Yakuza'' games' engine, with Creator/TakayaKuroda, the voice of ''Yakuza'' protagonist Kazuma Kiryu, portraying Kenshiro.

[[folder:Web Comics]]
* The action-oriented ''Webcomic/JetDream'' title spawned two spin-offs: ''It's Cookie'', a teen humor comic starring T-Girl Cookie Jarr, and My Jet Dream Romance, a romance comic that focuses on the love lives of the T-Girls.
* ''Webcomic/{{Precocious}}'' has a spinoff ''Webcomic/CopperRoad'', about the character Kaitlyn Hu and the "other side of the class" that lives on Copper Road.
* ''Webcomic/BasicInstructions'' once played with the concept in the strip "How to Create a Spin-Off", with the idea of ButtMonkey Rick getting his own comic. It was never meant to seriously take off, but the man who inspired Rick did use the character's popularity to briefly run his own spin-off blog called "Asking the Wrong Guy", playing Rick answering reader's questions.

* ''WebAnimation/OneMinuteMelee'' is a spin-off of Website/ScrewAttack's ''WebAnimation/DeathBattle''. While ''Death Battle'' is made up of roughly 20 minute-long episodes where the hosts put [[ShownTheirWork exhaustive research and comparisons into two combatants and their respective strengths, skills and weaknesses, and decides the winner based on that]], ''OMM'' is far more simply a matchup between two fictional combatants where the fights last no longer than 60 seconds and the winner is determined by AuthorAppeal. It's basically meant for ''DB'' fans who are JustHereForGodzilla.
* The edutainment ''WebVideo/TheBenHeckShow'' had the 2011 [[VerySpecialEpisode special]] HalloweenEpisode ''Ghost Hunting with Ben Heck!'', which is a thinly veiled pilot for the Pinball/AmericasMostHaunted pinball.
* ''WebVideo/TheHappyVideoGameNerd'': His 'SSFF' and 'Is it really that bad?' series of videos, usually featuring his friend Calvin. They're all improvised, edited-for-length-and-highlights videos of Derek playing various games not featured on HVGN.
* Website/TheAvocado is an unofficial spinoff of [[Website/AVClub The AV Club]], created by commenters on that site looking to create their own venue for pop culture reviews and discussion. Was originally called "The AV Club After Dark", but the initials AVCAD over time morphed into the word AVOCADO.

* The Creator/PBSKids series WesternAnimation/DanielTigersNeighborhood is a spin off to Series/MisterRogersNeighborhood complete with a similar opening.
* ''WesternAnimation/TotalDramaPresentsTheRidonculousRace'' is a spinoff of ''WesternAnimation/TotalDrama'' with four of the contestants from the latter (Noah, Owen, Geoff and Leonard) appearing to compete and a few cameos from the old cast here and there.
** ''WesternAnimation/TotalDramaDaycare'', which was revealed on December 19, 2017, serves as the second spinoff to ''Total Drama''.
* ''WesternAnimation/TheLEGOBatmanMovie'' follows the life of a secondary character from ''WesternAnimation/TheLEGOMovie'': Franchise/{{Batman}}.
** ''WesternAnimation/{{Unikitty}}'' is another ''LEGO Movie'' spin-off, featuring secondary character Unikitty.
* ''WesternAnimation/{{Arthur}}'' got a spinoff in the form of ''Postcards from Buster''.
* Though can be surprising for some people, ''WesternAnimation/{{Daria}}'' is a spin-off of ''WesternAnimation/BeavisAndButthead''. She was originally a recurring classmate of theirs and would make cynical remarks about their stupidity. Her own show kicked off when her family moved from Texas to the East Coast. While ''Beavis And Butthead'' may have had a larger pop culture impact, ''Daria'' was a much more intelligent {{dramedy}}, examining the pains and insecurities of adolescence. To this day it retains a cult following and a very vocal fanbase.
* ''WesternAnimation/ShaunTheSheep'' is a spin-off from ''Franchise/WallaceAndGromit'' using the Shaun character of one of their shorts. ''WesternAnimation/ShaunTheSheep'' at the same time has an spin-off with ''WesternAnimation/TimmyTime'' with Timmy the lamb as the protagonist of a show for toddlers.
* If you don't know that the ''[[WesternAnimation/TinyToonAdventures Tiny Toons]]'' had a spin-off series named ''The Plucky Show'' with the character of Plucky as the protagonist, don't feel bad. A lot of people don't like it as the show was not very popular and ran for only one season. Although the term "spin-off" might be an overstatement considering that most of the show's epsiodes consisted in clips from the original cartoon.
* Due to the Pinky and the Brain sketches' popularity in ''WesternAnimation/{{Animaniacs}}'', a spin-off series with them was made: ''WesternAnimation/PinkyAndTheBrain''. Then a [[{{Crossover}} crossover]]/spin-off was made, called ''WesternAnimation/PinkyElmyraAndTheBrain'', with the [[WesternAnimation/TinyToonAdventures Tiny Toons]]' character Elmyra in probably one of the most questioned moves ever done in animated television.
* The common consensus among fans is to consider ''WesternAnimation/DarkwingDuck'' as a spin-off of ''WesternAnimation/DuckTales'' as the character of Launchpad Mc Quack appears in both but is one of the protagonists in the former. Nevertheless according to WordOfGod; show creator Tad Stone, ''WesternAnimation/DarkwingDuck'' happens in a different universe than ''WesternAnimation/DuckTales'' with Launchpad as just an alternate version. If this is canonical inside the Disney Animated Universe, of course, is up to debate.
* ''WesternAnimation/MyLittlePonyEquestriaGirls'' is a spin-off of ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', taking place in a parallel universe and starring the teenage human equivalents of the main characters. WordOfGod states that while both works are canon to each other (Sunset Shimmer was indeed Celestia's previous student, Starswirl did banish the sirens to the human world, etc.), the team deliberately avoids writing ''Equestria Girls'' plots that could affect the main universe for simplicity's sake.
* ''WesternAnimation/DonaldDuck'', ''WesternAnimation/{{Goofy}}'', and ''WesternAnimation/{{Pluto}}'' were each the stars of their own animated shorts, and are possibly the earliest examples of spin-offs in WesternAnimation, being spin-offs of the ''WesternAnimation/MickeyMouse'' shorts.
